About This Item
The Pentair 98211400Z is the OEM replacement 1/4-20 plated brass hex nut for the Pentair FNS Plus D.E. Filter series, Hi-Flow Valve series, and Sta-Rite Multiport Top Mount Valve.
⚠️ IMPORTANT: QUANTITY REQUIRED VARIES BY EQUIPMENT
The Hi-Flow Valve (models 261049, 261050, and 261142) requires 8 of this nut per valve. The FNS Plus Filter and Sta-Rite Multiport Valve each require 1. Confirm the quantity needed for your specific equipment before ordering.
This hex nut secures key assemblies on filter and valve equipment where a corrosion-resistant fastener is required. A failed or corroded nut can compromise the clamping force on filter bands, valve covers, or manifold assemblies, leading to leaks or structural loosening under operating pressure. Match the part number on your existing hardware before ordering to confirm thread specification (1/4-20).

Pro Tip
When servicing Hi-Flow Valves, order a full set of 8 nuts in a single transaction — these fasteners are typically replaced as a complete set during valve disassembly. Inspect the mating bolt threads at the same time; if the bolts show corrosion or thread damage, replace them alongside the nuts to ensure consistent clamping torque across the valve assembly.
